Brush extension handle coupling

ABSTRACT

The wooden coupling has a substantially square cross section and is provided with a standard screw socket in one end for receiving the end of an extension rod handle, and a sponge rubber sleeve in a bore in its other end for receiving a brush handle so as to extend its reach to remote places which could otherwise not be reached without the use of a step ladder or some other cumbersome supporting apparatus onto which the painter would have to climb in order to reach them.

It has therefore been necessary to use a step ladder or, someother elevating apparatus to enable the painter to reach these areaswith a cut-in brush.

It was discovered that much time and effort could be saved by the use ofa simple coupling which could be mounted on the end of the conventionalroller extension rod handle normally carried in the painter's kit, theouter end of which coupling being provided with a bore having a spongerubber sleeve into which a cut-in brush handle could easily be insertedand firmly held for use in reaching the areas along the ceiling cornersfrom the floor without the need of a step ladder or other elevatedsupport means. Thus a painter having this coupling in his kit would needno ladder or other cumbersome scaffolding to lug around with him to hispainting jobs.

No coupling of this type could be found in the prior art. The closestreference found was Pat. No. l,237,056 issued to J. H. Kitchen on a guncleaner attachment, disclosing a coupling for a gun bore brush the shaftof which has a screw threaded end for fixing into one end of thecoupling, the other end of which has a screw socket for receiving theend of the extension rod.

The object of the present invention is to enable a painter to save muchtime and effort on jobs normally requiring the use of ladders orscaffolding, without hauling such cumbersome equipment around to thesejobs, and using, instead, a simple brush handle extension coupling onthe end of the conventional rod extension handle to hold a small brushfor reaching the distant areas of his paint job without the necessity ofclimbing on any supporting equipment.

A further object is to make the coupling rectangular in shape so as toprovide easy handling, stacking and packing.

Other objects will become apparent in the following detailed descriptionof this invention, as illustrated in the accompanying drawing.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 shows a conventional roller witha conventional extension rod handle.

FIG. 2 shows a preferred form of the novel brush holder coupling used onthe end of a conventional extension rod handle, and

FIG. 3 is a central cross-sectional view of the coupling.

DESCRIPTION OF THE PREFERRED EMBODIMENT The conventional paint roller,as shown in FIG. 1, has a handle 10 and a roller 12. A screw socket isprovided in the end of handle 10 for the reception of the screw end 28of an extension rod handle 14 for use in painting ceiling and high wallcorner areas not reachable with the roller 12, since the use of theroller normally does not reach the area strips along the corners wherethe walls and ceiling meet, and it is necessary to paint these areaswith a cut-in brush. It was found that a cut-in brush could be mountedat the end of the conventional extension rod handle by means of thenovel coupling into which the brush handle could be easily inserted andfirmly held for reaching the remote areas without climbing on anysupporting equipment.

Such coupling 16 is shown in FIGS. 2 and 3 as being a block of woodhaving a substantially square crosssection with a sponge rubber sleeve24 mounted in a bore in one end 20 of the block for receiving the handleof a brush 18, and a screw socket 26 in the other end 22 of the blockfor receiving the screw end of a conventional rod extension handle 14.

Obviously, the coupling can be made of other suitable materials insteadof wood, such as plastics, hard rubber or even metal, and the sleevecould have an oval shaped cross-section to match the shapes of thebrushes used.

Many other obvious modifications in form and structure as well asassembly of this coupling may be made without departing from the spiritand scope of the present invention.

What is claimed is:

l. A paint brush extension handle coupling comprisa block of suitablematerial having a substantially square cross-section and being ofsufficient length to provide for connecting sockets in its oppositeends,

the connecting socket in one end consisting of a bore having a sleeve ofresilient sponge material for receiving and frictionally holding thehandle of a conventional paint brush, and

the connecting socket in the other end having an internal screw threadfor receiving the screw end of a conventional extension rod handle.

2. An extension handle coupling as defined in claim said block materialbeing wood.

3. An extension handle coupling as defined in claim said sleeve materialbeing sponge rubber.

4. An extension handle coupling as defined in claim the corners of thescrew socket end of said block being rounded off.
